LangChain - Document Loading

Consider this custom loader code:

from langchain.document_loaders.base import BaseLoader

class ExampleLoader(BaseLoader):
    def load(self):
        return ["page1", "page2", "page3"]

loader = ExampleLoader()
docs = loader.load()
print(docs)

What will be printed?

AA string 'page1page2page3'

BAn error because load must return Document objects

CAn empty list []

D['page1', 'page2', 'page3']

Step-by-Step Solution

Solution:

Step 1: Analyze load method
It returns a list of strings: ["page1", "page2", "page3"].
Step 2: Check print output
Printing docs will output the list as is.
Final Answer:
['page1', 'page2', 'page3'] -> Option D
Quick Check:
load returns list, print shows list [OK]

Quick Trick: load returns list, print outputs list directly [OK]

Common Mistakes:

Assuming load must return Document objects only
Expecting concatenated string output
Thinking an error will occur on print
